After delete still **** mpg

[Biggreystroker]

I have a 08 250 ccsb with hot damn tunes and still getting almost stock mpg. Anyone know why or could help me out. I don't know if this makes any difference but the #8 injector sticks when it's cold. Any help would be great thanks

Hand calculated?

Lots of threads on here with different people saying that they are only getting a few MPG better than stock with the deletes. Don't know if you were looking for some sort of miraculous fuel economy or not but the deletes seem to be performance oriented first with fuel economy as a secondary factor/benefit.

It's all hand cal. Would the ret of the exhaust help or different tuning like kem?

Alot of it has to do with your driving habits and whether your driving more city than highway. Also if your using H&S try a different transmission tune, i.e. schedule 2.

I have the one with the converter locks up in 4 and med

I went from 10-11 to 13-15, depends how I drive, realistically that's still a HUGE change. Consider this, even if you were to "Only" gain 2mpg if you were getting 10 before is a 20% increase...... So exactly what are your numbers?

Ive seen 18mpg on the hwy with rpms lower than 2k, and a VERY easy foot. Almost too slow in the acceleration dept. Its all driving habits with these trucks, b/c tuned, they are just itching to dump some serious fuel and make power.

Town driving is gonna suck no matter what. I live in a small town and it's literally accelerate, brake, repeat everywhere you go. Adds up to about 9-11 mpg in town. Best thing I've found to do is watch the lie I meter and if I'm doing something that makes it go down do something else. Lol

Much as we all know the lie-o-meter is not accurate, it is a good tool to at least gauge the performance of your truck! I use mine to gauge how the truck is running, though there are times when ya just have to play (like blowing away a 300ZX turbo just because you can. lmao).

Been an interesting first 6 weeks with my truck, learning how to drive it without having 5mpg as my average fuel economy.
